Positive Door-Latch Housing Mechanism

      Described is a hardware implementation that provides a positive
door latch housing mechanism to protect electronic components from
the elements.  The design includes an O-ring to seal the unit and a
hold open feature to facilitate assembly of electronic components.

      The objective of the design is to seal the door housing by
designing a groove at the perimeter of the door so that an O-ring can
be installed.  Fig. 1 shows a cut-away side view of the positive door
latch housing mechanism.  The mechanism consists of chassis 10, Door
11, snap device 12 and O-ring 13.  O-ring 13 is installed around the
inner periphery of the door to provide a seal.  Positive retention is
attained at the bottom of door 11 through the use of snap 12.  Snap
12 is made up of an angled surface that mates to a corresponding
parallel surface on chassis 10.  Door 11 is installed by snapping it
onto chassis 10 so as to reduce assembly time.

      Fig. 2 shows an isometric view of the positive door latch
housing mechanism.  At the center of the door, there is a small
protrusion 14 that provides a means of holding the door open while
circuit cards or cables (not shown) are being connected.
